Since the URI <htpp://jmvanel.free.fr/jmv.rdf#me> ( that's me ) has a foaf:currentProjet and a foaf:homepage , it is inferred that he is an interesting-contact . To confirm this, one can either use the user Knowledge Base display in tools to see the whole KB. Or one can use the N3 shell to ask this query (just paste it with Ctrl-V) :
